I use Pocketbook. It opens just about anything - epub, mobi, pdf, pdb, and many more formats. Just get a book anywhere and copy it via USB. Or send it as an email attachment to your special address and it will download automatically. You can even replace the reading app with another relatively easily, if you want.

I very clearly remember "mortal wombat" as one of the insults in Tropic Thunder when I saw it in a cinema. But it was never there when I watched it later. Am I crazy or did they change the movie later?

Korolev is the father of the Soviet rocket program, argubly its most important person, somewhat akin to von Braun in the USA. He's a designer of R7, direct predecessor of Soyuz that is still flying people to space. You know the shape when the boosters/first stage of Soyuz disconnect from the central stage? It's called Korolev's cross to this day. It's definitely named after the scientist. And anyway, russians didn't have a king, they had a tzar.

By the way, while logged in, you can switch the user to a guest on the same instance. That way, you can easily switch between a logged-in and logged-out view. I don't know what it would do to your filters. I guess it won't help you, but might be usefull anyway.

I realised I have a sort of explanatory image at hand.

[–] lemming 2 points 1 week ago (1 children)

It has a part that is embedded in a mitochondrial membrane and works as a rotor. The other part is sticking out from the membrane and is responsible for synthesis of ATP from ADP and phosphate. An off-axis part of the rotor pushes the stator, it changes shape and pushes ADP and phosphate together, until they fuse to ATP.

To make the rotor move, it makes use of membrane potential. One side of the membrane has a lot more H⁺ (just protons, really) than the other. The excess H⁺ want to go to the other side. The membrane doesn't let them through. It is hydrophobic on the inside, so it does't let through anything charged (like H⁺) or polar (like water). This is the potential and it has quite a lot of energy. ATP synthase lets the H⁺ through by binding them to the rotor in the membrane in a particular place and releases them in another in such a way that forces the rotor to turn almost a full turn before they can leave and stops it from rotating the other way. As mentioned, the rotation is transfered to the stator, changing its shape and thus creating ATP. As a side note, multiple H⁺ are bound on the rotor along its circumference, so each rotation is powered by the potential energy of multiple protons.

Of course, it's a bit more complicated than that, but I don't think there's anything downright wrong or misleading in what I wrote. I hope I managed to make it understandable. Also, I recommend animations of the synthase on youtube.

One suggestion for securing your base before leaving is to make a construction tank. Tanks can be driven remotely and have equipment grid. You can put personal roboport in there and use it as your clumsy impersonation for building outside your roboport coverage from anywhere.

To me, it's obvously a trilobite :-)

Do you really need so may crushers? So far 3 are enough for me. I have very little experience, but it successfully went to all 3 first planets without much problem on my first try, only Gleba suffered from too little electricity.

Huh, good point, I never thought about that. Makes sense. I only ever heard about options to get shares when the company becomes publicly traded. Of course, publicly traded is what I meant.

Do the owners also get money based on the shares?

[–] lemming 2 points 2 weeks ago (3 children)

Which shareholders do you mean? SpaceX is private company, no shares.

Launch vehicle development by NASA is by their own admission slower and more expensive. It's no coincidence that the whole industry started moving forward much faster when a driven private company with financial interests at heart and without strong dependence on politicians started their own serious development.

As for the tax money paid to SpaceX, NASA simply bought services. They also helped with development. But whatever the expenses were, they were much lower than they would be if NASA did it the old way. By the way, the old way is similar, but instead of SpaceX, the money went to Boeing, Lockheed Martin etc. and there wasn't a limit on how much money it will be in advance. Now you know that if the costs exceed the agreed sum, it won't be paid by public money, but by the company. As seen with Starliner, which went so badly that Boeing said they are never doing fixed-price contracts ever again. They are used to the excess money paid from the public budget. In exchange for these advantages to the public, SpaceX can use the vehcle developed unther the contract on their own, without NASA. Therefore you can get missions such as Polaris, Inspiration4 or Axiom. Your opinion on these may be different, but I think private missions and influx of private money into spaceflight is good for spaceflight in general. It makes it more financially sustainable and more efficient.

I think it's supposed to be a better-paid test flight. It sound like nobody dares to send a crewed test flight and Boeing doesn't want to lose yet more money on uncrewed test flights.

To date, the company has reported losses of $1.85 billion on Starliner. As a result, Boeing has told NASA it will no longer bid on fixed-price space contracts in the future.

Wow, they really messed up big time and obviously don't think they can do better. I really wish SpaceX had competition, but they really don't. Sad.

That's the case for most species.

As a very specific and highly functional example of critical viral proteins in other organisms, there wouldn't be any placental mammals without viruses. https://en.m.wikipedia.org/wiki/Placenta

Mammalian placentas probably first evolved about 150 million to 200 million years ago. The protein syncytin, found in the outer barrier of the placenta (the syncytiotrophoblast) between mother and fetus, has a certain RNA signature in its genome that has led to the hypothesis that it originated from an ancient retrovirus: essentially a virus that helped pave the transition from egg-laying to live-birth.

Hello,

let's try and make a cog wheel on the Canvas. Space is getting limited, but I believe we still might squeeze in.

Here's a template (after moving to a new area): https://canvas.fediverse.events/#x=921&y=276&zoom=1&tu=https%3A%2F%2Fi.imgur.com%2FgbA1i7V.png&tw=43&tx=536&ty=339&ts=ONE_TO_ONE
